    Abstract: SARS-CoV-2 infections can induce kidney injury and glomerulopathy, with the most common pathology findings being acute tubular injury and collapsing glomerulopathy. Here we describe a rare case of membranous nephropathy in a man in his late 70s presented with nephrotic syndrome and rapidly progressive kidney dysfunction 1 month after SARS-CoV-2 infection. Phospholipase A2 receptor antibodies were positive. He was treated with rituximab, with proteinuria control. We review the cases reported in the literature.

    Abstract: Gastrointestinal tuberculosis is an uncommon entity, in which clinical presentation can be widely variable, from mild and nonspecific symptoms to an acute abdomen and gastrointestinal bleeding. Gastric involvement by 〈 i 〉 Mycobacterium tuberculosis 〈 /i 〉 is rare, especially when it occurs without other recognized infectious foci – primary gastric tuberculosis – with only a few reported cases. Endoscopic findings can be very heterogeneous, from areas of hyperemia to pseudotumor lesions. We present a case of primary gastric tuberculosis in an immunocompetent patient, in which the absence of an epidemiological context and nonspecific endoscopic findings led to a delay in the diagnosis. Bite-on-bite biopsies proved to be essential, allowing to obtain samples from deeper layers of the submucosa where 〈 i 〉 M. tuberculosis 〈 /i 〉 was identified. This case aimed to increase awareness for this entity, especially in endemic countries or regions with a high prevalence of tuberculosis since the diagnosis is based mainly on a high index of suspicion.

    Abstract: We present 3 cases of autoimmune liver disease in human immunodeficiency virus (HIV)-infected patients and describe the different diagnostic and therapeutic approaches used in each case. The first patient was diagnosed with primary biliary cholangitis (PBC) with features of autoimmune hepatitis (AIH), requiring second-line therapy due to incomplete response to ursodeoxycholic acid. The second patient was diagnosed with AIH with features of PBC and had the particular challenges of presenting with advanced liver fibrosis and having a past history of disseminated cytomegalovirus infection. The last case concerns an AIH with acute liver injury, successfully treated with corticosteroids and azathioprine. Recently, the number of patients on antiretroviral therapy (ART) for HIV disease has increased significantly. Therefore, more patients with this chronic infection have been diagnosed with autoimmune diseases, leading to concerns regarding immunosuppressive therapies in this population. With these cases, we alert for these increasingly incident diseases and support the safety of immunosuppressive therapies, provided that HIV is suppressed with ART.

    Abstract: Os tumores oncocíticos da supra-renal são neoplasias pouco frequentes. Atualmente existem 147 casos publicados. Os autores descrevem o caso de um homem de 34 anos admitido no hospital por lombalgias e febre. À observação identificava-se massa no quadrante superior esquerdo do abdomen. Os doseamentos das hormonas da supra-renal foram normais e a angiotomografia abdominal mostrou lesão retroperitoneal esquerda com 145 x 157 x 128 mm com extensas áreas necrosadas e hemorrágicas. O doente foi submetido a ressecção cirúrgica completa da lesão. O tumor pesava 1495 g e o exame anatomo-patológico concluiu tratar-se de tumor oncocítico da supra-renal com potencial maligno incerto. A maioria dos tumores oncocíticos é não funcionante e devem ser considerados no diagnóstico diferencial de tumores do córtex da supra-renal. O comportamento biológico e o seu prognóstico são variáveis e ainda estão mal estabelecidos. A propósito da raridade deste tipo de tumores os autores fazem uma revisão da bibliografia publicada.
